The utility model provides an among the technical scheme, hinge 100 connects a body 300 and main part 200, and one side of a body 300 is equipped with panel 400, rotates at a body 300 and opens the activity stroke of main part 200, drives hinge arm 120 and actuating arm 130 action, and the setting of first guiding mechanism 150 and second guiding mechanism 170 can convert the rotation of hinge arm 120 into the removal of moving member 160, and moving member 160 and panel 400 link realize then that panel 400 shifts up along with opening of a body 300. The utility model provides a hinge 100 has the characteristics that the transmission is simple reliable, and the structure is easily made, low in production cost.

In addition, the electrical equipment further comprises a main body 200, a door body 300 and a panel 400, wherein the main body 200 is provided with an inner cavity; the door 300 is rotatably connected to the main body 200 through the hinge 100 to open or close the inner cavity; the panel 400 is movably disposed at one side of the door 300; the first guiding mechanism 150 and the second guiding mechanism 170 cooperate with each other, so that in an active stroke of the door 300 rotating to open the inner cavity, the driving arm 130 moves along with the rotation of the hinge arm 120, the first driving end 131 of the driving arm 130 moves along the first guiding groove 152 of the first guiding mechanism 150 and approaches the door 300, and the second driving end 132 of the driving arm 130 moves along the second guiding groove 172 of the second guiding mechanism 170 and drives the moving member 160 to move in a direction away from the hinge 100, so that the panel 400 moves relative to the door 300 in a direction away from the hinge 100.

In the present design, the main body 200 may be a housing structure of an electrical device, and may also be a body of an electrical device, such as a body of the embedded dishwasher 1. The body 200 is formed with an inner cavity having an opening, which may be formed at any portion of the body 200, for example, at the top or any side of the body 200. For the convenience of understanding, in the following embodiments, the opening is formed at the side of the main body 200, and the opening is disposed forward for example.

The door 300 is connected to the main body 200 and movably disposed with respect to the opening to open and close the opening during a movement stroke thereof. The door 300 can move relative to the main body 200 in various ways, such as translating and/or flipping. In an embodiment, the door 300 has an installation end and a movable end, which are oppositely disposed along a panel surface thereof, the installation end is rotatably installed at one side of the opening, and a rotation axis thereof extends along a length direction of the side of the opening, so that the movable end can rotate towards the opening direction to cover the opening and rotate away from the opening direction to open the opening. Specifically, for example, when the electrical equipment is installed and placed in the vertical direction, the bottom end of the door 300 forms the installation end, the top end of the door 300 forms the movable end, the bottom end of the door 300 forms the installation end, and the hinge 100 is arranged at the installation end in the downward direction. When the opening is disposed forward as described above, the turning direction of the door 300 is also forward and backward, and specifically, the turning direction may be forward to open the opening, and backward to close the opening.

The panel 400 is movably disposed on one side of the door 300, and since the panel 400 and the door 300 are both substantially plate-shaped, they are stacked along the thickness direction, that is, the front panel surface of the door 300 and the rear panel surface of the panel 400 are at least partially stacked, and the door 300 and the panel 400 have a moving stroke substantially translating along the stacked panel surfaces. Specifically, the door 300 may be provided to be translated with respect to the panel 400, but generally, the panel 400 is basically translated with respect to the door 300, and the panel 400 is translated along the front panel surface of the door 300. For convenience of understanding, the moving direction of the panel 400 relative to the door 300 is defined as a first direction.

For those skilled in the art, when the door 300 is opened, that is, during the moving stroke of the moving end rotating away from the opening, the panel 400 moves along the front panel surface of the door 300 in the direction away from the installation end; in the moving stroke of the movable end rotating to be close to the opening, the panel 400 moves along the front panel surface of the door body 300 toward the direction close to the mounting end. The panel 400 may be a decorative hanging panel, or may be another panel structure that can move relative to the door 300. In this embodiment, since the panel 400 is opened along with the rotation of the door body 300 and moves from the mounting end to the movable end, it can be avoided that the interference collision occurs between one end of the panel 400 close to the mounting end and peripheral structures, such as a cabinet body and the ground.

In the present design, the first guide mechanism 150 and the second guide mechanism 170 are configured to: in the rotation stroke of the door 300, the driving arm 130 is caused to drive the panel 400 to move relative to the door 300.

As described above, it can be understood that the moving stroke of the rotation of the door 300 herein includes the stroke of opening the door 300 and the stroke of closing the door 300, and in the moving stroke of the rotation of the door 300, the driving arm 130 rotates relative to the panel 400, that is, as long as either one of the driving arm 130 and the panel 400 can rotate relative to the other, it can be regarded as a rotational connection. When the door body 300 is opened, because the hinge arm 120 is directly or indirectly connected with the door body 300, the door body 300 can drive the hinge arm 120 to move, and by arranging the first guide mechanism 150 between the mounting member 140 and the driving arm 130 and arranging the second guide mechanism 170 between the driving arm 130 and the moving member 160, the first guide mechanism 150 and the second guide mechanism 170 jointly act on the driving arm 130, so that the driving arm 130 is driven to rotate relative to the panel 400 and the panel 400 is driven to move relative to the door body 300.

Specifically, in the moving stroke of the rotation of the door 300, the driving arm 130 moves along with the rotation of the hinge arm 120, and the first guide mechanism 150 restricts the rotation of the driving arm 130 along with the rotation of the hinge arm 120. For example, in the opening stroke, since the hinge arm 120 and the driving arm 130 are rotationally connected (e.g., rotationally connected by a pin), when the hinge arm 120 rotates, the driving arm 130 can be driven to approach the door 300, and thus, the driving arm 130 can be considered to follow the movement, and the movement can also be considered to be a certain degree of following rotation, and the limitation of the rotation of the driving arm 130 following the rotation of the hinge arm 120 can be understood as the inconsistent motion amplitude of the driving arm 130 and the hinge arm 120, for example, the driving arm 130 and the hinge arm 120 can rotate relatively, the driving arm 130 can not rotate but the hinge arm 120 rotates, the rotation amplitude of the driving arm 130 can be smaller than the rotation amplitude of the hinge arm 120, the rotation direction of the driving arm 130 can be different from the rotation direction of the hinge arm 120 (the driving arm 130 rotates reversely relative to the hinge arm 120), the driving arm 130 can be limited to only perform linear reciprocating motion but the rotation of the hinge arm 120, and so on, correspondingly, when the hinge arm 120 rotates, a constraint is applied to the driving arm 130, so that when the driving arm moves along with the rotation of the hinge arm 120, the second guiding mechanism 170 is engaged, so that the driving arm 130 approaches to the direction approaching to the door 300, the panel 400 is urged to move relative to the door 300 in the direction away from the hinge 100 when the door 300 is opened, and the panel 400 is urged to move relative to the door 300 in the direction toward the hinge 100 when the door 300 is closed.

In addition, during the rotation stroke of the door body 300, the second guide mechanism 170 causes the moving member 160 and the driving arm 130 to rotate relatively, so as to cause the moving member 160 to move along with the movement of the driving arm 130. That is, the second guide mechanism 170 serves as a reversing mechanism that can convert the rotational movement of the hinge arm 120 into the movement of the moving member 160 via the driving arm 130. The second guiding mechanism 170 may be used to switch between two movement modes, i.e., rotation and translation, and may also be used to switch the movement direction and limit the movement stroke, so that the entire rotation stroke of the driving arm 130 just drives the panel 400 to move to a set position relative to the door 300 during the opening stroke of the door 300; in the closing stroke of the door 300, the entire rotation stroke of the driving arm 130 just drives the panel 400 to move to the reset position relative to the door 300.

Compare in utilizing structures such as multistage gear drive to realize that panel 400 opens or closes the technical scheme who removes along with the door body 300 among the prior art, the technical scheme that this embodiment provided can only through the constraint effect between hinge arm 120, actuating arm 130, installed part 140 and the moving member 160 in the hinge 100, just can realize the linkage between the rotation of the door body 300 and the panel 400 removal, and simple structure is reliable, and the hinge 100 structure is easily made, low in production cost, the transmission is simple, the jamming phenomenon is difficult to appear, high reliability.

In this design, the hinge 100 connects the door 300 and the main body 200, and is disposed closer to the mounting end than the movable end. The hinge 100 connects the panels 400. The hinge 100 can be with the door body 300 is relative the rotation of main part 200 converts the drive the panel 400 is relative the door body 300 translation to make the door body 300 open the door and close the door action, with the translation of panel 400 is stepped down and is reset the action and form the linkage, need not additionally to set up other drive devices, helps the structure to simplify and reduces the energy consumption.

In the hinge 100, the rotation shaft 110 may be disposed on a rotation axis of the mounting end of the door 300, and based on this, according to actual requirements, the mounting end may be further disposed to be rotatably mounted on the main body 200 through the rotation shaft 110, and the hinge arm 120 may be rotatably mounted on the main body 200 through the rotation shaft 110. Alternatively, the shaft 110 may be spaced from the axis of rotation of the mounting end. In general, the position of the rotating shaft 110 is not limited, and it is only necessary to ensure that the hinge arm 120 can rotate relative to the main body 100, for example, the rotating shaft 110 is fixed on the mounting member 140, the mounting member 140 is arranged on the main body 100, the hinge arm 120 can be rotatably arranged on the rotating shaft 110, that is, the rotating shaft 110 connects the mounting member 140 and the hinge arm 120 (the rotating shaft 110 is fixedly arranged on the mounting member 140, the hinge arm 120 can be rotatably connected to the rotating shaft 110, or the rotating shaft 110 is fixedly arranged on the hinge arm 120, the rotating shaft 110 can be rotatably connected to the mounting member 140),

specifically, referring to fig. 3 to 4 and 10, in an embodiment, the hinge arm 120 includes a first arm 121, a second arm 122 and a connecting portion 125 connecting the first arm 121 and the second arm 122, the first arm 121 is connected to the door 300, the second arm 122 is connected to the main body 200, and the connecting portion 125 is connected to the rotating shaft 110.

Based on the above, the first arm 121, the connecting portion 125, and the second arm 122 may be arranged to extend in a collinear manner, so that the hinge arm 120 is substantially straight. However, since the hinge arm 120 is disposed near the mounting end, when a corner is formed between the door 300 and the main body 200, the hinge arm 120 is disposed at the corner, in order to adjust the moment arm of the hinge arm 120, in an embodiment, the first arm 121 and the second arm 122 may be further disposed to form an included angle, and a connection portion 125 is formed at the intersection of the first arm 121 and the second arm 122, so that the hinge arm 120 is substantially bent, and can be better adapted to the mounting environment of the corner, and better force transmission is achieved.

The first arm 121 and the door 300 may be fixedly connected. The connection manner of the two is not limited, and may be one or more of screw fixation, snap fixation, adhesive fixation and adsorption fixation, for example. Specifically, as shown in fig. 10, a threaded hole is formed in a position of the first arm 121 corresponding to the door 300, and the first arm 121 and the threaded hole in the door 300 are sequentially connected through a screw connector, so that the first arm 121 and the door 300 are connected and fixed.

The second arm 122 may be elastically connected to the main body 200. Generally, the second arm 122 may be coupled to the body 200 by a resilient structure, such as a pull cord and/or a tension spring. Based on this, the second arm 122 may be provided with a hook portion, and the second arm 122 may be detachably connected to the pull rope and/or the elastic structure such as the tension spring through the hook portion, so as to be more convenient to disassemble and fix.

The connecting portion 125 has a shaft hole, the shaft hole may have a notch on one side, and the rotating shaft 110 is rotatably engaged with the shaft hole. The connecting portion 125 may further include a reinforcing rib protruding from the periphery of the shaft hole, and the reinforcing rib may increase the connection fitting strength at the shaft hole.

In addition, the driving arm 130 is rotatably connected to the hinge arm 120. Specifically, referring to fig. 3 to 4 and fig. 11, in an embodiment, the driving arm 130 has a first driving end 131, a second driving end 132 and an intermediate section 133 located between the first driving end 131 and the second driving end 132. The first driving end 131 and the second driving end 132 may be disposed oppositely, or may be disposed at an interval of any angle. The first driving end 131 is disposed closer to the body 200, and the first guiding mechanism 150 is disposed between the first driving end 131 and the mounting member 140; the second driving end 132 is disposed closer to the door body 300, the second guiding mechanism 170 is disposed between the second driving end 132 and the moving member 160, and the middle section 133 is rotatably connected to the hinge arm 120.

Thus, the movable stroke of the first driving end 131 is restricted by the first guide mechanism 150. It can be understood that, since the panel 400 has a moving stroke moving relative to the door 300, during the rotating opening process of the door 300, the movement of the hinge arm 120 causes the position of the stressed driving arm 130 to change. The first guide mechanism 150 constrains the driving arm 130 to limit a rotation track and a rotation stroke of the driving arm 130. It can be understood that, under the constraint of the first guiding mechanism 150, the driving arm 130 rotates to a set stroke relative to the hinge arm 120 to drive the second driving end 132 to generate position change, the position change of the second driving end 132 may be a linear track or an arc track, and the second guiding mechanism 170 is configured to constrain the linear translation of the moving member 160 along the first direction, so as to achieve the purpose of translating the linkage panel 400 along the first direction through the opening and closing movement of the door 300.

In the present embodiment, during the rotation stroke of the door 300, the driving arm 130 rotates following the rotation of the hinge arm 120. That is, the hinge arm 120 is rotatably connected to the driving arm 130, and the hinge arm 120 is linked with the driving arm 130 to rotate through the rotational connection therebetween.

Specifically, the driving arm 130 is rotatably mounted on the hinge arm 120 by a rotation connection shaft. The rotation connecting shaft may be coaxially disposed with the rotation shaft 110, that is, it is equivalent to that the driving arm 130 rotates around the rotation shaft 110 following the rotation of the hinge arm 120.

Alternatively, as in the present embodiment, the rotational connection portion of the driving arm 130 is spaced apart from the rotating shaft 110, so that during the rotational stroke of the door body 300, the driving arm 130 revolves around the rotating shaft 110 following the rotation of the hinge arm 120. In this way, the driving arm 130 can move toward the door body 300 following the hinge arm 120, and the driving arm 130 approaches in the first direction as a whole, which further facilitates driving the moving member 160 to translate in the first direction.

In an embodiment, in a moving stroke of the door 300 for opening the main body 200, at least the second driving end 132 of the driving arm 130 approaches the door 300. Because the second driving end 132 is connected to the moving member 160 and the second guiding mechanism 170 is connected therebetween, when it is ensured that at least the second driving end 132 of the driving arm 130 approaches the door body 300, the second driving end 132 can realize the movement of the moving member 160 along the first direction through the second guiding mechanism 170.

The specific structure of the first guiding mechanism 150 and the second guiding mechanism 170 is not limited in this embodiment, for example, the specific structure may be a sliding pin and a sliding groove which are matched with each other, as long as the constraint on the driving arm 130 can be achieved, and the driving arm 130 can be driven to act, so that in the opening stroke of the door body 300, through the arrangement of the first guiding mechanism 150 and the second guiding mechanism 170, the moving track of the first driving end 131 gradually approaches the door body 300, so that the driving arm 130 can drive the second driving end 132 to drive the panel 400 to move relative to the door body 300 along the first direction and the direction away from the installation end in the process of the rotation opening of the hinge arm 120. On the contrary, in the closing stroke of the door body 300, the movable end rotates to be close to the main body 200, and through the arrangement of the first guide mechanism 150 and the second guide mechanism 170, the driving arm 130 can drive the second driving end 132 to drive the panel 400 to move relative to the door body 300 along the first direction and the direction close to the installation end in the process of rotating and closing the hinge arm 120, and the moving track of the first driving end 131 gradually gets away from the door body 300.

It is understood that the first guiding mechanism 150 may be disposed between the driving arm 130 and the main body 200, for example, the sliding pin or the sliding groove is directly formed on the main body 200, and the sliding groove or the sliding pin is correspondingly disposed on the driving arm 130. So configured, the hinge 100 has fewer components and occupies less space, which is beneficial to maximize the size of the electrical equipment.

The first guide mechanism 150 is provided with a slide pin or a slide groove 123 by a mounting member 140 provided separately from the main body 200. The mounting member 140 may be coupled to the body 200 by bolts, welding, or the like. Compared with the technical solution of directly processing on the main body 200, the present embodiment cooperates with the driving arm 130 through the separately disposed mounting member 140, and the first guiding mechanism 150 is disposed between the mounting member 140 and the driving arm 130, so that the hinge 100 is easier to manufacture and has low production cost. And the existing electrical equipment structure can be used, mold opening is not required again, research and development cost is reduced, and the hinge 100 and the main body 200 are also beneficial to applying different materials.

With continuing reference to fig. 1, 3-5, specifically, the mounting member 140 can be fixed to the main body 200 by bolts or the like. The first guide mechanism 150 includes a first guide pin 151 and a first guide groove 152 respectively disposed on the driving arm 130 and the mounting member 140, and specifically, the first guide pin 151 may be disposed on the first driving end 131 of the driving arm 130, the first guide groove 152 may be disposed on the mounting member 140, or the first guide pin 151 may be disposed on the mounting member 140, and the first guide groove 152 may be disposed on the first driving end 131 of the driving arm 130, as long as the first driving end 131 and the mounting member 140 can be engaged with each other. The first guide pin 151 is matched with (inserted into) the first guide groove 152, so that in the opening stroke of the door body 300, the moving track of the second driving end 132 gradually approaches the direction of the door body 300. On the contrary, in the closing stroke of the door body 300, the moving track of the second driving end 132 is gradually far away from the door body 300.

With the above structure, in the opening stroke of the door 300, when the first driving end 131 of the driving arm 130 is pulled to move in the direction approaching to the door 300, the first guiding pin 151 and the first guiding groove 152 cooperate to limit the rotation, so as to drive the second driving end 132 of the driving arm 130 to drive the moving member 160 to move in the direction of the moving end along the door 300. On the contrary, in the closing stroke of the door body 300, when the first driving end 131 of the driving arm 130 is drawn to move in the direction close to the main body 200, the first guide pin 151 and the first guide groove 152 cooperate to limit the rotation, so as to drive the second driving end 132 of the driving arm 130 to drive the moving member 160 to move along the direction of the door body 300 to the mounting end. In this embodiment, the first guide pin 151 and the first guide groove 152 are arranged to realize the linkage between the rotation of opening or closing the door 300 and the movement of the panel 400 moving along the door 300, and the structure is simple and reliable, and compared with complex transmission structures such as multi-stage gears, the structure is not easy to be stuck, and is easy to manufacture and low in production cost.

Preferably, in this embodiment, please refer to fig. 1 to 6 with continued reference, the first guide pin 151 is disposed at the first driving end 131, the first guide groove 152 is disposed at the mounting member 140, and the first guide groove 152 is bent from the main body 200 toward the door 300. The specific shape of the first guide groove 152 may be various, for example, the first guide groove may be a straight line shape or an arc shape, or a combination of the straight line shape and the arc shape, as long as the restriction can be formed on the driving arm 130, so that the second driving end 132 of the driving arm 130 drives the moving member 160 to move along the door 300 towards the installation end or the moving end in the process of rotating and opening or closing the hinge arm 120.

As also described above, the first guide groove 152 may be linear (entirely linear, without significant bending), and when the first guide groove 152 is linear, the first guide groove 152 may extend laterally or be disposed obliquely from the main body 200 toward the door body 300. Of course, the first guide groove 152, which is curved, may have a lower resistance than a straight line, and may be designed such that the movement of the panel 400 is not uniform. For example, in the present embodiment, the first guide groove 152 extends in an arc shape, so that the first guide pin 151 slides more smoothly, and the occurrence of the clamping phenomenon is avoided.

In addition, the shape of the first guide groove 152 can be simply and adaptively designed to meet the design requirement of the movement stroke of the panel 400 relative to the door 300, for example, the first guide groove 152 can be divided into different groove segments to adapt to the installation environments of different electrical equipment and the door opening mode, and the shapes and the extending directions of at least part of the groove segments can be set differently, so that not only can various stroke designs be realized, but also the design is easy to realize, the development cost is low, and the reliability is high.
